Why people convert IST to Los Angeles time

Scheduling a call from IST to Los Angeles: a 10:00 AM start in IST lands at 9:30 PM in Los Angeles the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -12h 30m gap: IST and Los Angeles have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Los Angeles is 8:30 PM in IST.
Watching a live event or market open: IST viewers need 8:30 PM in Los Angeles to catch a 9:00 AM start there, and 12:30 PM if the event is anchored to IST.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -12h 30m gap is not.
With a -12h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week IST takes the early slot, the next week Los Angeles does.
Los Angeles: Clocks fall back on Sun, Nov 1, 2026. Any meeting series spanning that date will shift by an hour in local time.
